Enhydro Quartz is quartz with water-filled internal cavities. Enclosed in negative voids within the stone, there may be a bubble of air which has evaporated out of the liquid as the growing quartz crystal cooled. If there is sufficient space enough to allow it, these air bubbles move within the cavity as the stone is rotated. These bubbles can also be carbon filled.
The largest Enhydro is a beautiful piece of quartz with lots of rainbows, bubbles and carbon. If you look closely in the 3rd video, you will see more carbon/bubbles floating near my thumb, that are not even marked. Measures 2.62" x 1.05"
The smaller Enhydros with red marker have carbon and the blue marker have just a bubble.
